Special Issue Information

Dear Colleagues,

Biomass is the basis for making renewable bioenergy, biofuels, and other bioproducts, and waste residues from harvesting (roots, trunks, branches, bark, needles, leaves and fruit), from manufacturing processes, or even from naturally killed trees can be used as sources.

There is a growing interest in using wood and non-wood biomass residues to obtain a wide range of renewable bioproducts, often in coproduction with bioenergy, chemicals, pharmaceuticals and nutraceuticals, renewable biomaterials, and other manufactured goods. Biomass is therefore an opportunity to generate added-value bioproducts from waste, always taking into consideration the sustainable conservation of ecosystems, avoiding the use of fossil fuels.

This Special Issue “Bioenergy and Forest-Based By-Products” aims to explore biomass-derived technologies and products, the possible new applications and commercial use of the new value-added “green” products, and the development of processes for forest regeneration improvement.

We are looking forward to informing the scientific and industrial communities of the cutting-edge research on the optimized processes for the development of added-value bioproducts and to identifying new markets for the emerging sustainable economy.

We invite you to publish your front-line results on how forest-based wastes can become efficient, sustainable, and economically viable feedstock for clean energy production, bioproducts development, and applications.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Forests is an international peer-reviewed open access monthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2600 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.

Massive use of wood biomass is usually associated with its long-term, large-scale storage in power plants and heating plants. Long-term storage of wood biomass (more than 3 months), in large volumes, brings risks from the point of view of human health or property treatment. This work aimed to verify how the long-term storage of wood chips from beech wood in small piles affects their energy properties and whether in this way it is possible to reduce the risk of fire by self-heating in piles and the volume of phytopathogenic spore production. Four experimental piles, each with a base of 4 × 4 m and a height of 2 m, were established. After 6 months, one of the piles was disassembled and samples from 0.5 m, 1.0 m, and 1.5 m height levels were taken for analysis. The results of the experiment confirmed that the energy properties of wood chips stored in small piles significantly deteriorate after more than half a year of storage. It has also been confirmed that the choice of this method of storing in smaller, spatially divided piles can lead to a significant minimization of the risk of spontaneous combustion and fire. The length of the storage period did not have a positive effect on the abundance of phytopathogen content in the stored piles. With the length of storage, only the number of identified harmful species of phytopathogens were changed and, at the same time, their number of colonies increased. Full article

Deforestation shows the constant environmental degradation that occurs worldwide as a result of the growth of economic activity and the increase in population. This research examines the causal link between renewable energy consumption, GDP, GDP2, non-renewable energy price, population growth and forest area in high, middle- and low-income countries. Based on data obtained from World Development Indicators, the autoregressive distributed lag model, with a time series, is used to examine the long-term cointegration relationship between the variables. The results justify the existence of a joint long-term relationship between the variables analysed for the middle-income countries and low-income countries. When the forest area is not at its equilibrium level, the speed of adjustment is slow (0.44% and 8.7%), which is typical of the nature of this natural resource. An increase in the consumption of renewable energy is associated with an increase between 0.04 and 0.02 square kilometres of forest cover, respectively. The research does not show evidence about the equilibrium relationship in the short term. Growth in renewable energy consumption is one of the main drivers for preserving the forest area. Therefore, those responsible for making economic policies must aim their measures towards the use of clean energy. Full article
